  • Patent number: 4141372
    Abstract: A vibrating feeder for feeding disc-like objects such as coins to a subsequent work station such as a coin sorter has a unitary box-like structure provided with a particularly contoured bottom. The bottom defines a main flow path and an auxiliary flow path leading to the main flow path which in turn terminates in an exit for the coins. The auxiliary flow path has longitudinally inclined fins for guiding coins to the main flow path while somewhat retarding the flow rate to avoid jamming of coins and to avoid an excessive flow rate. Each flow path also includes one or more troughs contoured so that a coin will not lie flat thereon. The feeder is inexpensive to produce, is simple in execution and operation and provides a controlled flow rate for coins or other objects to the subsequent work station.
